The Pueblo Chemical Depot is a chemical weapons storage site located in Pueblo County, Colorado, United States.

The depot houses 2,611 tons (2,369 metric tons) of mustard agent in approximately 780,000 munitions, equivalent to about seven percent of the original chemical material stockpile of the United States.[1][2] The current course of action for the Pueblo Chemical Agent-Destruction Pilot Plant, included in the President's Fiscal Year 2010 Budget Request, will allow for acceleration of the project schedule. After systemization and pilot testing of the facility, destruction operations are expected began in spring 2015 with full-scale operations to begin later in the year. Destruction of all munitions is expected to be complete in 2019. The plant will operate until all the chemical weapons have been destroyed. Closure activities (shut-down, dismantling, and restoration of site) are slated to be wrapped up by 2022. The plant will use neutralization with a hot caustic solution followed by bacterial biotreatment to destroy mustard agent. [3] This is far outside the deadline set by the Chemical Weapons Convention (April 2012).
